Preformed thermoplastic indicia for airport runways and taxiways
Disclosed is an alkyd resin-based pre-manufactured thermoplastic airport runway signage that is applied in relatively large sections onto an airport runway. The pre-manufactured preformed thermoplastic formed as a continuous sheet and wound onto a take-up spool. The runway surface is prepared with a CCS an epoxy primer and the preformed thermoplastic is unwound from the take-up spool and positioned onto the runway surface. When the pre-manufactured thermoplastic signage is in a desired location it is initially rolled conforming to the runway surface. Heat is applied to the rolled surface to a preferred temperature with an infra-red (IR) heater to melt and adhere the pre-manufactured thermoplastic signage into the runway surface.
The present disclosure describes a preformed or in some cases a hot applied thermoplastic marking composition comprising a planar top surface portion and a planar bottom surface portion that are coplanar to each other, wherein said bottom surface portion is directly applied to a substrate via application of heat or pressure or both heat and pressure and wherein said top surface portion comprises an intermix that exits throughout said thermoplastic composition and includes large grit size aggregate in the range of about 8 to about 20 mesh or grit size, thereby reducing or eliminating tire tracking while also improving long-term skid resistance.
The present disclosure describes preformed pre-bonded thermoplastic sections comprising smaller articles where the articles and sections have planar top surfaces and planar bottom surfaces that are coplanar to each other. There is also an adhesive backing layer on the coplanar bottom surfaces so that the adhesive backing layer bridges and bonds coplanar bottom surfaces to form unified pre-bonded thermoplastic signage thereby preventing dislodging or separation of the signage during handling, movement, and/or transportation before or during application of the pre-bonded signage. The articles when properly sequenced, matched, and combined, together makeup the sections such that when the sections are also sequenced and matched the sections combine to form thermoplastic signage with a final pattern wherein the planar top surfaces include sequential features necessary to visibly aid in quick assembly of one or more unified thermoplastic signages.

The invention herein pertains to pavement marking patterns and the application thereof to roads, streets, walkways and the like. Various pattern designs for the markings are available to replicate layers of bricks, cobblestones, horizontal signage, logos and other components. The marking patterns are composed of two or more independent sections, the first section is a grid representing for example, the mortar joints in a brick wall. The second sections or inserts, for example represent bricks which are contained within the grid. As the first and second sections are generally formed from different colored, preferably thermoplastic materials, a hot melt adhesive spray is utilized on the bottom surface of the marking pattern to bridge the intersections between the first and second sections to maintain the integrity of the marking pattern for convenience during handling and application to a substrate. Preferably the hot melt spray adhesive has approximately the same softening point range as the pattern sections to accommodate heat treatment of the marking pattern during application of the marking pattern to the substrate.

This application relates to a method of applying a thermally settable coating to a patterned substrate, such as an asphalt surface. The coating is applied in one or more preformed thermoplastic sheets and heated in situ to conform the thermoplastic material to the pattern formed in the underlying substrate. In one embodiment of the invention a pattern is formed in the asphalt surface using a removable template which is impressed into the asphalt when it is in a pliable state. The pre-formed sheets are then applied to the patterned surface and gradually heated. In an alternative embodiment of the invention the template is impressed into the pre-formed sheet and asphalt surface simultaneously after the sheet has been heated to a suitable temperature in situ. A bond reduction agent may be used to minimize adhesion between the template and the heated thermoplastic material. In a further alternative embodiment of the invention the thermoplastic material may be stamped after it has melted and partially cooled to cause the thermoplastic to more precisely conform to the underlying pattern.

A detectable pavement warning assembly includes a web having a plurality of projections attached to one another by linear connectors, a planar cover with a series of apertures for receiving the projections therethrough and an adhesive sheet. In use a rigid substrate such as a sidewalk is selected, and a primer is applied. The web, cover and adhesive sheet all pre-assembled are placed on the primed substrate. Next, the warning assembly is heated with an open flame to soften and fuse the pavement warning assembly with the primed substrate. The projections will remain extended sufficiently above the cover to provide a warning to pedestrians that walk thereon, such as when approaching a traffic area or other hazard.
This application relates to a method of applying a thermally settable coating to a patterned substrate, such as an asphalt surface.
